Peter your correct in saying audio quality is different in sound quality between studio's and track's played occasionally makeing modulation level's inconsistent , it's more noticeable in the car listening volume , plus electrical noise increases . 648 is definitely lacking a bit compression , overall audio level is lower than in the past few years 😭 Being truthful we don't listen to Caroline's output much anymore because the enjoyment of listening on AM isn't up to standard anymore , The Harris is capable of 140 positive peaks but when pushed with hard modulation it seemed that something is not right , is that because output power is below its minimum threshold of 10KW or something to do with internet connection quality , Maybe Rob A could let us know
